The destruction of ACh receptors makes skeletal muscle less responsive to nerve stimulation and more likely to prematurely fatigue. With fewer ACh receptors available to bind to ACh, the skeletal muscle cell membrane potentials have a more difficult time reaching the threshold potential and initiating contraction. Thus, the normal degree of fatigue noted during repetitive nerve stimulation is exacerbated in an individual with myasthenia gravis.
The individual heartbeat, or contraction, can be modified by input from the sympathetic and parasympathetic nervous systems. This modification can include increased or decreased contraction ratios, increased or decreased stroke volume and increased or decreased rate of contraction.

Intensity of a wave is proportional to the square of its amlitude so it should decrese when the amplitude is decreased.
The muscle is said to undergo Fatigue.
decreased width of the H band during contraction
Decreased force production
Intensity of sound is dealt as volume in case of radio sets. Intensity is directly proportional to the square of amplitude. So as volume is turned down, intensity is reduced and so the amplitude is decreased.

I would expect the light bulb to fail.
The electromagnetic wave is "modulated" (changed) to represent the signal. For example, in AM (amplitude modulation), the strength (amplitude) of the wave is increased or decreased, according to the signal.
as the amplitude increases the waves get closer together like an accordion being squeezed...so the vibrations become faster (or higher pitched if we're talking about sound) if the amplitude is decreased the waves spread out and the vibration is slower and lower in pitch
Increased blood glucose, decreased GI peristalsis, and increased heart rate and blood pressure.
